It maybe remarkedthatcneor bothofthe holes.lntheiraihe wh ch receive the bolts each other around a common fulcrum tijby manipulating nuts 7 which are arranged in clamping relation to one of said levers on. a threaded stud Swvhich projectstrom the other, and it may also be true of the spring 9 acting on said lever structure toshittfit in one direction and the means shown -for manually shifting it in. the v othendirection, the latter means including a threaded rod 10 connected withsaid lever structure anda nut 11 on the threaded portion oftherod and seated against the frame. The brakestrap 12 may follow a knownconstruction in so far as it includes a metalstrip having a leatherlining 12 (Fig. 7),.but the strip is preferably somewhat thicker and hence stiller than usual.

13 is a standard which rests on one side 13 arewenlarged (as at l3", Fig. 3) .to :per-

,mitthc upper end of the standard to. be adbrake-strap. parallel with the reel axis may .be afforded by, forming horizontal slots 1 t in"1 i ito::receive thebolts 1st). The'con- .structiouis such as to permit the brakestrap to be readily set- .to the required ebrakingipressurefor beaming or for warp- :ing,by-zinanipulatingnut 11, as will be ob- ,VlOIlS. It is also such that the attendant can raise the brake-strap to idle position (broken line, 'Fig. l), as (1t des1red)- when warping, either by manipulating said nut, or, 11 he and relocking it in its new position by inserting said pin in the. appropriate holes 17". The standard 13 and its associated parts atford an anchorage means for one end of the brake-strap.

The anchorage means forthe other end of the brake-strap is afforded as in my patented construction bythe lever structure 4 5, the lever 5 of which has a stud 21 fixed in two arms 5 thereof and to which the terminal poi-ti on of the brake-strap is immediately attached. Said terminal portion or end of the brake-strap is afforded by a fiat bar 20 secured to the strap proper by bolts 20 and having an eye 20 receiving and pivoted on said stud, such terminal portion or end be ing thus inflexible; the bar, which upstands from the stud, has on its outer side a rib 20 and also a flat fin 20, the former near its upper end and the latter at its pivot end.

One of the objects of my present invention is to provide for adjustment of this end of the brake-strap parallel with the reel was so a as to true the brake-strap transversely of the port for maintaining in upright position the said terminal portion of the brakestrap, being L-shaped in cross-section and having an eye 22. whose axis is parallel with the plane of its wall 92 and which receives a stud 23 fixed in the frame parallel with the reel axis, the eye having a set screw 24 to secure it fastto the stud. At the free end of this keeper its wall 22 is deflected toward the brakewheel to form a jaw 22 and opposite to and extending parallel with this jaw is another jaw 22 formed by a pin fixed in the casting, the two jaws forminga narrow space (Fig. 9) which receives the inflexible terminal portion of the strap. Wall 22 has a slot 22 which receives the tin 20, whereby said terminal portion and the keeper are interlocked for movement together lengthwise of the reel axisand the keeper aii'ords means for adjusting the said terminal portion of the strap transversely of the periphery of the brake-wheel.

lVhen the brake-strap is elevated it is my purpose to have it stand substantially if not entirely out of contact with the brake wheel at any point; it has enough stiffness so that its arcuate portion'will retainsubstantially the semicircular form, and so the strap will not touchthe brake-wheel when it is elevated if only its depending tangent portions are prevented from buckling and are held properly spaced from the brake-wheels periphcry. It is also my purpose to provide against tl e strap sagging over transversely of the brake-wheel periphery when it is elevated to a position perhaps clear of the bralze-wheel flanges. Therefore both the inflexible portion of the brake-strap and the anchorage means afforded by 13 and its associated parts, the former held upright as described by the keeper 22, extend close up to the horizontal diameter of the brake-wheel, and each is adjustable in a way to urge the corresponding end portion of the strap toward or from and thus space it the desirable distance from the brake-wheel periphery, to wit, by tilting of 13 and by tilting keeper 22 on its stud or pivot 23. To insure against any sagging over of the strap transversely of the brake-wheel periphery due to possible looseness at 21 I prefer to provide the 1nentioned rib 20 and have it engage a notch 22" in the support 22 (Fig. 9).

It is to prevent buckling of the brakestrap at the right hand end portion thereof. in Fig. 1 when the other end portion is ele vated that I form the first-named end portion inflexible, pivoting are its anchorage means, and support it in an upright position by the keeper 22; andthe construction is thus such that ii the anchorage means 4 -5 is a lever the same can function as herein set iorth'without any binding of the inflexible end portion of the brake'strap in the guide then ali'ord'ed by the keeper.

Having thus fully described my invention what I claim and desire to secure by Ilctters Patent is:

1. In a machine of the class described having a reel revoluble on a horizontal axis, the combination of a still flexible brakestr-ap adapted to extend over and in peripheral contact with a part of the reel, and anchorage means to which the ends ol said strap are attached, one such end being adapted to depend from the reel and being rclcasably held by the corresponding anchorage means and shiftable up or down relatively to such means when released thereby to slacken or tighten the strap.

2. In a machine of theclass described haw ing a reel revoluble on a horizontal axis, the combination of a brake-strap adapted to extend overand in peripheral contact with a part of the reel,'anchorage means to which one end of the strap is connected, the other end of the strap being adapted to depend from the reel, and other anchorage means including a relatively fixed part and a supporting member for said other end of thestrap attached thereto and moving therefrom, anchorage means for said end portions, one of said end portions being inflexible and being pivoted to the anchorage means, and means, engaging said inflexible end portion at a point removed from the pivot between the same and the anchorage means for supporting said end portion in an upright position.

In a machine of the class described having a reel revoluble on a horizontal axis, the

combination of a brake-strap extending over the reel, means at the end portions of the strap to hold the same taut, said strap at one end portion thereof being shittable relatively to the holding means lengthwise of the reel axis, and means to adjust said strap at said end portion in. the direction in which it is shittable,

5. In a machine of the class described having a reel revoluble on a horizontal axis, the combination of a stiff flexible brakestrap extending over the reel and having one end portion movable to tanten or slacken the strap and also having one end portion depending from the reel, means at the end portions of the strap to hold the strap taut, and a vfixed keeper engaging said depending end portion between the reel and said means and holding said portion upright.

(3. In a machine of the class described having a reel revolnble on a horizontal axis, the combination of a stiff flexible brake-strap ex tending over the reel and having one end portion movable to tanten or slacken the strap and also having one end portion depending from the reel, means at the end portions ot' the strap to holdthe strap tent, and a fixed keeper engaging said depending end portion between the reel and said means and holding said portion upright, said keeper portion movable to tanten or slacken the strap and also having one end portion depending from the reel, means at the end portions of the strap to hold the strap taut, and a. fixed keeper engaging said depending end portion between the reel and said means and holding said portion upright. said keeper being adjustably shittable around an axis parallel with the reel axis and engaged with said depending portion to urge the same toward or from the reel on shifting of the keeper.

8. In a machine of the class described having a reel revoh ble on a horizontal axis, the combination of a. stiff flexible brake-strap extending over the reel and having one end portion movable to tauten or slacken the strap and having one end portion depending from the reel, means at the end portions of the strap to hold the strap taut, and a fixed keeper engaging said depending end portion between the reel and said means and holding said portion upright, said keeper being adjnstabiy shittable lengthwise of the reel axis and also adjnstably shift-able on a pivot parallel with the reel axis and having said depending portion engaged therewith to partake of its shitting both lengthwise of and around said pivot.

In testimony whereof I aflix my signature.
